HDMI Features

Transition-Minimized Differential Signaling (TMDS) – When digital data is transmitted, especially over long distances, it is susceptible to noise and signal loss. TMDS is a way of encoding an HDMI signal to protect it from interference as it travels from source to receiver. It works like this:

• The sending device encodes the signal, organizing the ones and zeros to reduce the chance that the signal will degrade.
• Two copies of the signal are transmitted over different internal wires, one an “out-of-phase” version of the actual signal.

Consumer Electronic Control (CEC) – This feature allows a user to control up to 15 connected HDMI devices using one remote controller. Most TVs and streaming devices support CEC, but it may be turned off by default. Manufacturers sometimes refer to CEC using their own branded term (e.g. Anynet+, Viera Link) so it may not be apparent that your device supports it.

High-Bandwidth Digital Content Protection (HDCP) – this authentication protocol allows a sending and receiving device to verify each other’s credentials (stored on each device’s Extended Display Identification Data (EDID). create a shared key that is used to encode and decode the data passing between them. This process, known as a handshake, happens almost instantaneously at the beginning of a session and ensures that an unauthorized device cannot intercept the data as it travels between two devices. In the United States, HDCP support is mandated by the Federal Communications Commission (FCC).

Display Data Channel (DDC) – The HDMI interface includes support for VESA DDC, a set of protocols that allow a source (a computer’s graphics card, for example) to ask a monitor what audio and video formats it can handle, and adjust settings on the monitor, such as brightness and contrast.
